Why do intraplate earthquakes tend to be less frequent and smaller than earthquakes at plate boundaries?

Earthquakes on plate boundaries happen more because the plates all move in different directions in a tectonic environment so they collide against each other which makes them more frequent. Earthquakes rarely happen in intra-plate environments but along faults in normally stable interior of the plates. If this doesn't make sense, ask me to reword it for you !
